[pymvpa] Help with map2nifti()

[Taku Ito]

Oh!  I did in fact have one, though it's the Zscore-mapper (I had
previously thought I checked 'mapper' in res[1].a, but perhaps it came out
incorrectly).  Though I realize Z-score mapper probably doesn't have a
reverse mapper, and perhaps that's the issue?  Is there a workaround you
may be aware of?

Thanks!
